The factors that cause an LCD to shift are dye fading and fluorescent bulb
aging. These are the type of factors that reprofiling is intended to
compensate for. Inconsistancies across the screen is an issue that profiling
does not deal with, but that's the same for CRTs as well.

2. Which LCD monitors would you recommend anyway and why?
Mitsubishi, LaCie and most of the others in that price range are good, as are
the Apple LCDs. The why is a bit difficult. Partly it is the gamut and even
brightness, partly the wide viewing angle without significant color shift,
and partly the layers in the screen. Tap on a cheap LCD and a lightning flash
will hit the entire screen, followed by a set of ripples spreading from the
touch point. A good screen does neither, and barely shows the touchpoint.

There are only a few LCD capable devices on the market currently. Of those
the EyeOne is the "midprice" solution, in the $600 range for the monitor-only
configuration, while the Spyder is the "affordable" solution at half that.

The cheapest ones do not profile accurately, if their viewing range is too
narrow. The midprice ones calibrate and profile acceptably, but have a
restricted viewing angle, and a lower quality display in general.

The better models are simply better... in brightness, range, detail, viewing
angle, consistancy across the screen, resolution, flicker, etc...

I'm not aware of a comprehensive list, tested for profilability as well as
other factors.

If the screen is good enough, then calibration makes a great deal of sense.
The most recent Titanium PowerBooks are well worth calibrating, though the
thinner screen (compared to desktop units) means you still have to move your
head up and down to be sure you are perpendicular to the portion of the image
you are studying to have the gamma correct.
